Binaural 6 Hz A soft start: brown noise, rain, a forest brook, and a few birds. Save it to keep your own version.

EqualizerLow to high

Ocean 22

A calm sea washing onto the shore. Gentler than breaking beach waves, steady enough for sleep.

Binaural 6 Hz 60

A binaural beat in the theta range, about 6 hertz. Headphones are required. It is a tone difference, not a medical treatment.
